Description

  The present invention relates to a discoloration inhibitor having an excellent inhibitory effect on discoloration of dyed hair, in particular, fading acceleration due to free residual chlorine contained in tap water, and a hair composition containing the same.

  In recent years, coloring to change hair color into various colors has been performed to make hair look beautiful, and there is a tendency for consumers to be interested in dyeing hair such as gray hair dyeing and fashion dyeing. In addition, hair dyeing techniques are being improved daily. However, the dyed hair that has been colored should maintain its color after the coloring due to discoloration problems such as discoloration, pigment disappearance, and pigment elution due to repeated exposure to ultraviolet rays such as sunlight and daily washing. There is a difficult problem (Patent Document 1).

  In order to maintain the color of dyed hair after coloring, a technique using a carboxybetaine-type amphoteric surfactant and a sugar-based non-surfactant (Patent Document 2), ether carboxylic acid and its salt, alkyl glucoside, sterol A technique using a derivative (Patent Document 3) and a technique using an amide betaine amphoteric surfactant and an anionic surfactant (Patent Document 4) have been reported. However, these cannot sufficiently suppress the discoloration of the dyed hair in the hair washing treatment, and do not sufficiently suppress the dye elution from the dyed hair.

  EXAMPLES The present invention will be specifically described below with reference to examples, but the technical scope of the present invention is not limited to these examples.

1. Elimination of free residual chlorine by fading inhibitor Test Outline The discoloration inhibitor of the present invention was evaluated for free residual chlorine scavenging action.

2. Experimental Method A test tube was mixed with 10 μL of the fading inhibitor of the present invention diluted with purified water and 890 μL of tap water. Thereafter, 100 μL of rapid DPD reagent (Kanto Chemical) prepared to 100 mg / mL was added and mixed well, and then the absorbance at 510 nm was measured with a microplate reader and calculated as the erasure rate.
Peach leaf extract (trade name: peach extract BG), linden extract (trade name: linden extract BG-J), ziou extract (trade name: ziou extract BG-J), manufactured by Maruzen Pharmaceutical Co., Ltd. Chimpi extract (trade name: Chimpi extract BG), Parsley extract (trade name: Parsley extract BG-J), Senkyu extract (trade name: Senkyu extract BG), Yukinoshita extract (Product name: Yukinoshita extract BG), Gayoi extract (Trade name: gaitou extract BG) and enmiso extract (enmiso extract BG) were used.

3. Results The results are shown in Table 1. Addition of 0.1% of any discoloration inhibitor of the product of the present invention showed a free residual chlorine scavenging activity of 50% or more.

1. Anti-fading effect of peach leaf extract against fading caused by free residual chlorine in dyed hair Test Outline The effect of peach leaf extract on the discoloration of dyed hair by free residual chlorine was evaluated.

2. Experimental Method Hair bleaching was performed on the bleached hair bundle using a commercially available oxidation hair dye (red) according to the attached instructions. The dyed hair was immersed in purified water as an untreated control and in purified water to which 10% hypochlorous acid was added as free residual chlorine. With these as basic conditions, conditions for the presence or absence of addition of 1% peach leaf extract (trade name: peach extract BG, Maruzen Pharmaceutical Co., Ltd.) were prepared for each condition. The dyed hair is immersed in each solution and shaken for 2 hours, then dried with a shampoo and a dryer. After repeating this for three cycles, the dyed hair is dried, and then the color of the dyed hair is measured by a color difference meter (CR- 13, Konica Minolta HD). The red index a ^* was evaluated as a color index.

3. Results No difference in color was observed between purified water and peach leaf extract. On the other hand, in the hypochlorous acid-containing solution, a significant decrease in color was observed compared to purified water, confirming acceleration of discoloration due to free residual chlorine. On the other hand, the color change was not recognized by adding 1% peach leaf extract. From the above, it has been clarified that the peach leaf extract has a remarkable discoloration suppressing effect on the discoloration of the dyed hair caused by repeated exposure to free residual chlorine.
